Abstract: A wireless peripheral mode is provided by a host system that communicates to a WiFi infrastructure and, utilizing the same WiFi RF subsystem, also communicates to peripherals. The host system may employ additional RF channels for communicating with high bandwidth peripherals, such as display devices, where high levels of QoS may be managed locally. The host system may be a conventional desktop computer system, a notebook computer system, a multi-media access point, a cell phone, a game machine, a portable game machine, a Personal Digital Assistant (PDA), a smart phone or any other type of device that benefits from accessing both a WiFi infrastructure and local peripherals.

Abstract: A digital display system consists of an image modulator and multiple light modulators. An image processing system processes an incoming data stream, scans processed data to an image modulator and controls for the light modulators. Other user inputs and sensors are used to affect the processing and controls. The timing for scanning the processed data into the image modulators is controlled along with the intensity and wavelength of the light modulators. The display system may implement a spatial and temporal image processing, digital shutter controls, rolling shutter controls, sequential color output, adaptive dynamic sensor feedback, frame rate matching, motion compensated field sequencing and a variety of other techniques to produce a high quality display output. The resulting display has improved image consistency, enhanced color gamut, higher dynamic range and is better able to portray high motion content.

Abstract: An efficient architecture for a virtual desktop system in a Virtual Machine Monitor (VMM) operating environment. In one embodiment, initially, a virtual desktop computer system utilizing one or more host computer systems provides one or more remote display systems with interactive graphics and video capabilities. The host computer system generally manages windows and frames that correspond to remote display systems and manages updating the remote display systems over a network connection. Preferred embodiments include a multi-display processor that is enhanced for VMM operating environments. VMM operating environments typically consist of different Virtual Machines (VMs) and a control layer known as the Virtual Machine Monitor (VMM) that manages the different VMs. Each VM is typically designed to be unaware of the existence of other VMs and the VMM is designed to provide the necessary abstraction, isolation and coordination between the different VMs to the physical platform hardware.

Abstract: A multi-display computer system comprises a host computer system that processes windowed desktop environments for multiple remote displays, multiple users or a combination of the two. For each display and for each frame, the multi-display processor responsively manages each necessary portion of a windowed desktop environment. The necessary portions of the windowed desktop environment are further processed, encoded, and where necessary, transmitted over the network to the remote display for each user. Embodiments integrate the multi-display processor with the graphics processing unit, network controller, main memory controller or a combination of the three. The encoding process is optimized for network traffic and special attention is made to assure that all users have low latency interactive capabilities.

Abstract: Image processing enhances display quality by controlling both the image modulator and the light sources. The image processing system utilizes a combination of user inputs, system configuration, design information, sensor feedback, pixel modulation information, and lighting control information to characterize the display environment on a per pixel basis. This per pixel characterization information is combined with one or more frames of the incoming real time display data. The image processing system processes each incoming pixel and produces a modified corresponding output pixel. Each pixel of each frame is processed accordingly. The image processing system also produces control information for the light sources. The light source control information can control individual lamps, tubes or LEDs, or can control a block or subset of the light sources. The resulting display has improved image consistency, enhanced color gamut, higher dynamic range and is better able to portray high motion content.

Abstract: System for accurately predicting the outcome of conditional branch instructions subject to execution in a pipelined processor digital computer. The system comprises a series of predictor stages utilizing different prediction algorithms. The stages are linked to successively refine branch predictions only where prediction accuracy from a previous stage is likely to be improved by a subsequent stage. Improvements to each stage and techniques for stage linkage are described.

Abstract: A graphical interface for visually specifying the behavior of combinations of finite-state and continuous-state actors. The state of an actor may be controlled by the states of other actors. The motion of continuous-state actors is constrained by functions represented as, and analogous to, grooves, sockets, pins, glue, springs, and boxes. These functions may be represented graphically on the actor so that the system of constraints is readily ascertainable to the user.

Abstract: A method and apparatus for direct manipulation of 3-D objects on computer display. This method and apparatus provides for a 3-D bounding region wherein the 3-D bounding region has sensitive areas which the user can select with a reference pointer such that when the user manipulates the reference pointer after selecting a sensitive area the 3-D bounding region and the object within it are manipulated with direct kinesthetic correspondence between the user's manipulation of the reference pointer and the bounding region and object manipulation.

Abstract: A series of devices for in vivo imaging of cellular architecture in a variety of tissues. A 200 MHz transducer is mounted on the tip of a cardiac catheter, gastroscope, colonoscope, bronchoscope, laparoscope or similar device, where it is moved mechanically to produce B-mode images of cells in the tissue. The ultrasound beam is focused in a subsurface region of tissue, and ultrasound which is backscattered from the focal zone is analyzed to produce images. Because heart motion may interfere with cardiac imaging, images are gated in mid-diastole for cardiac applications.

Abstract: The present invention facilitates the Dynamic Random Access Memory (DRAM) refresh function in a less obtrusive manner than in the prior art. The present invention facilitates the refresh function during idle time when the DRAM is not busy handling read or write transactions. If insufficient idle time exists then the present invention will force a refresh operation thus ensuring that all memory cells are maintained in a properly charged state.

After resonator enclosures have been pre-formed they advance to a second stage. A jig form molds pre-formed resonator bulbs and concrete together in a panel molding region to form a resonator panel.

Abstract: An interface module for coupling a VMEbus channel to a Universal Common Data Point channel and exchanging data signals in either direction. The module responds to protocol handshake signals from the originating channel, accepts a multi-word message-block, and provides handshake signals to notify the destination channel of message to be delivered. The module then transfers the message-block to the destination channel.

Abstract: A photovoltaic relay which includes a unique pull down circuit for rapidly turning off the relays field effect transistor(s). The pull down circuit discharges the gate-to-source capacitance of the relay's field effect transistors by turning on a thyristor by turning off a light-activated switch connected between the gate and the cathode terminals of the thyristor. In one integrated circuit embodiment, the light-activated switch is energized by the same light source which activates the photodiode stack which drives the relay. The presence of the pull down circuit does not effect the turn on time of the relay.

A plurality of least significant bits of said digital word stored in said latch are applied to a logic circuit. A ring counter is utilized to indicate which section of the output signal is currently being generated.
